Wayne transmigrated, but something went a little wrong during the process.

After floating in the sky above an otherworldly continent for over a hundred thousand years, he felt that he probably needed a physical body to be considered a proper transmigrator. However, he never expected that after finally succeeding, he would have to drag this new body out of a coffin and face two completely dumbfounded great-great-great-great... great-granddaughters as well as a world that is on the verge of the end of its era.

[A kingdom building, tech building action novel where the MC from Earth transmigrates into the body of a Grand Duke in a world of dragons, elves, mages and knights and starts reforming his territory with universal education, science and abolishing slavery etc. At the same time, he's fighting against evil cults, the gods, various nobles and preparing to face the apocalypse. The MC is likeable, actually uses whatever knowledge he has. He's not completely OP and depends on a large number of people. He uses his brain far more often than his predecessor's supposedly legendary strength. The side characters are memorable and well developed. There are a few 'genius' characters who turn his technological ideas into reality and even improve upon them quite a bit. The antagonists are quite smart. Their actions are always logical and they actually win some of the time.]
